Rxv667 trigger out repair

Hello friends,

I accidentally shorted the trigger out of my rxv667. Now it measures 0v. Is there a most likely component on this circuit which protects against shorted over currents? Many thanks!

If you are now getting 0V, it kinda suggest there is no short circuit protection.
Most likely you've blown one or more transistors, hopefully the +18V regulated supply is ok.
I'd start by checking the output of the _18V regulated supply, by measuring dc voltage at the
emitter of that top transistor (apology, lousy graphic), if lucky, that's the only blown part.
